MOISTURE IN COMPRESSED AIR
Moisture is a normal by-product of compressing air. As the moisture builds during compressor use, it can be carried though the air hose. When
using paint spray gun or sandblasting gun, the use of a special filter to remove moisture from the air line is highly recommended. Moisture in
the compressed air will cause water spots in paint jobs and cause blasting media to clog the sandblasting gun.
